I can comment with only first item in while loop, When I tried to comment with another item it's always display alert box You know you need to write a comment right?. I think it can't get comment text on another item in my loop, What's wrong with my code?
I've got this comment code from this link.
My code:
Ajax in index.php
<script type="text/javascript">
$(function () {
// Alert(event.timeStamp);

$('#name-com').focus();
});
/* When you click on the cancel button */
$('.bt-cancel-com').click(function () {
$('.the-new-com').val('');
$('.new-com-cnt').fadeOut('fast', function () {
$('.new-com-bt').fadeIn('fast');
});
});
// On post comment click
$('.bt-add-com').live('click', function (evt) {
var comment_on_id = $("input[name=comment_on_id]");
var theCom = $("textarea[name=comment-text]");
var theName = $('#name-com');
var theMail = $('#mail-com');
if (!theCom.val()) {

} else {

I copied this code from stackoverflow it working fine when i upload multiple file through it. but i cannot send other parameter with it . it only upload the file but dont send the other parameter. i tried different way but i am unable to send the data.
My code is below but i dont send the second parameter of NewDir:foldername to my php file
This is my javascript code///////////
function OnProgress(event, position, total, percentComplete){
//Progress bar
console.log(total);
$('#pb').width(percentComplete + '%'); //update progressbar percent complete
$('#pt').html(percentComplete + '%'); //update status text
}
$(document).ready(function(){
$('#files').change(function(){
var files = $('#files')[0].files;
var foldername = $('#Reciter_Name').val();
var error = '';
var form_data = new FormData();
var bar = $('.bar');
var status = $('#status');
var percent = $('.percent');
if(foldername == ''){
alert("Your Don't enter any name");
return false;
}
for(var count = 0; count<files.length; count++)
{
var name = files[count].name;
var extension = name.split('.').pop().toLowerCase();
if(jQuery.inArray(extension, ['mp3']) == -1)
{
error += "Invalid " + count + " Mp3 File"
}
else
{
form_data.append("files[]", files[count]);
}
}
if(error == '')
{
$.ajax({
url:"<?php echo base_url(); ?>index.php/admin/upload", //base_url()
return http://localhost/tutorial/codeigniter/
method:"POST",
data:{form_data,NewDir:foldername},
contentType:false,
cache:false,
processData:false,
beforeSend:function()
{
// $('#uploaded_files').html("<label class='text-success'>Uploading...</label>");
status.empty();
var percentVal = '0%';
bar.width(percentVal);
percent.html(percentVal);
},
uploadProgress: function(event, position, total, percentComplete) {
var percentVal = percentComplete + '%';
bar.width(percentVal);
percent.html(percentVal);
},
success:function(data)
{
$('#uploaded_files').html(data);
$('#files').val('');
}
})
}
else
{
alert(error);
}
});
});
This is my php code given below///////////
function upload()
{
sleep(3);
if($_FILES["files"]["name"] != '')
{
$output = '';
$config["upload_path"] = './uploads/audio/';
$config["allowed_types"] = 'mp3';
$config["overwrite"] = TRUE;
$this->load->library('upload', $config);
$this->upload->initialize($config);
for($count = 0; $count<count($_FILES["files"]["name"]); $count++)
{
$_FILES["file"]["name"] = $_FILES["files"]["name"][$count];
$_FILES["file"]["type"] = $_FILES["files"]["type"][$count];
$_FILES["file"]["tmp_name"] = $_FILES["files"]["tmp_name"][$count];
$_FILES["file"]["error"] = $_FILES["files"]["error"][$count];
$_FILES["file"]["size"] = $_FILES["files"]["size"][$count];
if($this->upload->do_upload('file'))
{
$data = $this->upload->data();
$output .= '
<input type="hidden" name="url[]" value="'.base_url().'uploads/audio/'.$data["file_name"].'" />
<input type="hidden" name="surahname[]" value="'.$data["file_name"].'" />
'.$data["file_name"].'
';
}
}
}
echo $output;
}
So please tell me how i can pass data from php file.
/////////////////////////////////////////////////////////////////
You just need to add
form_data.append('NewDir',foldername);
Before assign form_data to ajax data variable
I want to do it so when a user clicks a checkbox it sets the tinyint value that's set in the database from 0 to 1 and vice-versa. My ajax.js:
function emailNextWithAddress(chk, address) {
var nextEmail, inside_where;
if (chk.checked === true) {
$.ajax({
url: "marca_enviado.php",
data: address,
type: "get",
success: function () {
nextEmail = document.createElement('input');
nextEmail.id = address;
nextEmail.value = address;
nextEmail.type = 'text';
nextEmail.name = 'email[]';
nextEmail.className = 'insemail';
nextEmail.style.display = 'inline-block';
inside_where = document.getElementById('addEmail');
inside_where.appendChild(nextEmail);
},
error: function () {
console.log("Erro!");
}
});
} else {
$.ajax({
url: "desmarca_enviado.php",
data: address,
type: "get",
success: function () {
inside_where = document.getElementById(address);
inside_where.parentNode.removeChild(inside_where);
},
error: function () {
console.log("Erro!");
}
});
}
return false;
}
And the part that I'm trying to update is(dbh.php is the connection to the database):
<?php
include_once 'dbh.php';
$id = $_GET['address'];
$updateEnviado = "UPDATE escolas SET Enviado = '$id'";
$result = mysqli_query($conn , $updateEnviado);
?>
In my index.php the part of the code that's being outputted is:
$execItems = $conn->query("SELECT Nome,EmailGeral,Enviado FROM escolas");
while($infoItems = $execItems->fetch_array()){
echo "
<tr style=\"border: 1px solid black;\">
<td>".$infoItems['Nome']."</td>
<td>".$infoItems['EmailGeral']."</td>
<td><input type=\"checkbox\" ".($infoItems['Enviado']?' checked':' ')." onclick=\"emailNextWithAddress(this, '".$infoItems['EmailGeral']."');\"/></td>
</tr>
";
}
?>
Note that I'm only interested in updating the checkbox.
I have a page with ajax pagination on it, I am currently able to check if the session exists and process accordingly. However, I cannot seem to remove the menu or reload the page properly if the session has expired. Only the menu remains and the login page shows in the small area where the table was.
Controller code
public function index()
{
$conditions = array();
$data = array();
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search(array('limit'=>$this->get_per_page()));
$data['user'] = $this->AccountModel->get_person($this->get_person_id());
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$this->load->view('layout/admins/common/header');
$this->load->view('layout/admins/common/navigation');
$this->load->view('layout/admins/common/title');
$this->load->view('layout/admins/common/errors');
$this->load->view('layout/admins/common/search');
$this->load->view('admins/documents/index',$data);
$this->load->view('layout/admins/common/footer');
}
public function search(){
if($this->input->is_ajax_request()){
if(!$this->logged_in()){
$this->index();
}else{
$conditions = array();
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$keywords = $this->input->post('keywords');
if(!empty($keywords)){
$conditions['search']['keywords'] = $keywords;
}
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$conditions['start'] = $offset;
$conditions['limit'] = $this->get_per_page();
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search($conditions);
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$this->load->view('admins/documents/ajax_pagination', $data, false);
}
}
}
My JS Code that is placed in the view
<script>
function searchFilter(page_num) {
page_num = page_num?page_num:0;
var keywords = $('#search').val();
$.ajax({
type: 'POST',
url: 'url/AdminDocuments/Search/'+page_num,
data:'page='+page_num+'&keywords='+keywords,
beforeSend: function () {
$('.loading').show();
},
success: function (html) {
$('#list').html(html);
$('.loading').fadeOut("slow");
}
});
}
function changeStatus(input){
var id = input;
$.ajax({
type:'POST',
url:'url/AdminDocuments/ChangeStatus/',
data:'id='+id,
beforeSend: function () {
$('.loading').show();
},
success:function(result){
console.log(result);
searchFilter(0);
$('.loading').fadeOut("slow");
}
});
}
function deleteDocument(input){
var id = input;
$.ajax({
type:'POST',
url:'url/AdminDocuments/Delete/',
data:'id='+id,
beforeSend: function () {
$('.loading').show();
},
success:function(result){
searchFilter(0);
$('.loading').fadeOut("slow");
}
});
}
</script>
i am assuming $('#list').html(html); code loads the html in the dom. instead of directly sending the html from php you can send a json containing the html as well the login status. like this.
$data = [
'login_status' => 1 // or 0,
'html' => $html // full html your are sending now
];
echo json_encode($data);
then in ajax success.
function searchFilter(page_num) {
page_num = page_num?page_num:0;
var keywords = $('#search').val();
$.ajax({
type: 'POST',
url: 'url/AdminDocuments/Search/'+page_num,
data:'page='+page_num+'&keywords='+keywords,
beforeSend: function () {
$('.loading').show();
},
success: function (response) {
var data = $.parseJSON(response);
if(data.login_status == 0)
{
window.location.href = 'redirect to login page';
}
if(data.login_status == 1)
{
$('#list').html(data.html);
}
$('.loading').fadeOut("slow");
}
});
}
controller method :
public function search(){
if($this->input->is_ajax_request()){
$conditions = array();
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$keywords = $this->input->post('keywords');
if(!empty($keywords)){
$conditions['search']['keywords'] = $keywords;
}
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$conditions['start'] = $offset;
$conditions['limit'] = $this->get_per_page();
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search($conditions);
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$html = $this->load->view('admins/documents/ajax_pagination', $data, true);
$res['html'] = $html;
$res['login_status'] = ($this->logged_in()) ? '1' : '0';
echo json_encode($res);

Here is my code:
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var ColorId = "1";
$( "#targetButton" ).click(function() {
$.ajax({
url: 'checkcolors.php',
type: 'post',
dataType: 'json',
success: function (data) {
var arr = data.msg.split(',');
arr.forEach(function(id){
$('#' + id.trim()).hide();
});
//$('#target').html(data.msg);
},
data: ColorId
});
});
});
</script>
<button type="button" id="targetButton">Send</button>
<div class="BlackAndWhite" id="24604682">24604682</div>
<div class="BlackAndWhite" id="24604682x">24604682x</div>
<div class="BlackAndWhite" id="24604679">24604679</div>
<div class="BlackAndWhite" id="24604621">24604621</div>
Here is how the result looks like from checkcolors.php:
24604603, 24604684, 24604640, 24604609, 24604682, 24604686, 24604681, 24604689, 24604602, 24604679, 24604680, 24604622, 24604685, 24604683, 24604621, 24604677, 24604688,
And here is the code from checkcolors.php:
<?PHP
$url = 'http://www.sportsdirect.com/dunlop-mens-canvas-low-top-trainers-246046?colcode=24604622';
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$DataVariants = $xpath->query('//span[#class="ImgButWrap"]/#data-variants')->item(0)->nodeValue;
$jsonStart = strpos($DataVariants, '[');
$jsonEnd = strrpos($DataVariants, ']');
$collections = json_decode(substr($DataVariants, $jsonStart, $jsonEnd - $jsonStart + 1));
foreach ($collections as $item) {
$ColVarId = $item->ColVarId;
$SizeNames = [];
foreach ($item->SizeVariants as $size) {
$SizeNames[] = $size->SizeName;
}
if (in_array("7", $SizeNames)) {
echo "$ColVarId, ";
}
}
?>
When i click the button i am watching the browser console for any warnings or errors but there are none. Somehow it is not working and i do not know why.
It is supposed to hide all div elements with the same ids given from the checkcolors.php response, but it is not working. Why ?
Can you please help me out?
Thanks in advance!
Try to change this line:
var arr = data.msg.split(',');
to this:
var arr = data.split(',');
In your php script "checkcolors.php", you must return a JSON file.
$res = array();
foreach ($collections as $item) {
$ColVarId = $item->ColVarId;
$SizeNames = [];
foreach ($item->SizeVariants as $size) {
$SizeNames[] = $size->SizeName;
}
if (in_array("7", $SizeNames)) {
$res[] = $ColVarId;
}
}
echo json_encode($res);
Then in your javascript, you replace arr by data.
data.forEach(function(id){
$('#' + id.trim()).hide();
});
I want to send a post form in Codeigniter when click a link:
My html code:
Delete
I want to do with post method because is more secure to do with csrf protection.
Thanks
Source: http://jsfiddle.net/iam_groot/aaeftkhv/
You need to create a global variable in html header for csrf protection:
<script>
var csrf_token_name = "<?php echo $this->security->get_csrf_token_name(); ?>";
var csrf_hash = "<?php echo $this->security->get_csrf_hash(); ?>";
</script>
Edit html link:
Delete row
And add this javascript code:
<script>
create_form_post = function(action, fields, target) {
if(target == undefined) {
target = '_self';
}
fields[csrf_token_name] = csrf_hash;
id_form = makeid();
$( '<form method="POST" action="'+action+'" target="'+target+'" id="'+id_form+'" style="display:none !important;"></form>' ).appendTo( "body" );
$.each(fields, function( k, v ) {
$( '<input name="'+k+'" value="'+v+'" type="hidden" />' ).appendTo( "form#"+id_form );
});
return id_form;
}
function makeid()
{
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for( var i=0; i < 9; i++ )
text += possible.charAt(Math.floor(Math.random() * possible.length));
return text;
}
$(document).ready(function() {
$("a.delete").click(function() {
if(confirm("¿Are you sure?")) {
action = $(this).attr('href');
delete_id = $(this).attr('id');
id_delete_form = create_form_post(action, {id: delete_id});
$("form#" + id_delete_form).submit();
}
});
});
</script>
Use AJAX
url = '<?php echo site_url('clientes/delete/'); ?>';
$('.delete').click(function(){
clientId = $(this).attr('id');
$.ajax({
type: "POST",
url: url,
data: { clientId: clientId }
});
})
In controller
if(isset($_POST['clientId'] {
$clientId = $_POST['clientId'];
} else {
$clientId = 'No data';
}
